What is a Portal?

 A Portal is an interactive web application used to share, store, and collaborate with information. You probably already use several Portals online without even realizing it. MySpace, for example, is an entertainment Portal directed at young people. But Portals aren't limited to entertainment; they can be powerful business tools as well.

How is a Portal different from a web site?

A Portal runs on the same technology most web sites use, but rather than sending information one way, a Portal is used to send information back and forth between users and administrators, making it a powerful tool for collaboration.
